' To aZZ whom, it may concern:

Be it known that I, FRANK EUGENE KEYES, of Newport, in'the county ofSullivan, of the State of New Hampshire, have invented a new and usefulImprovement in Machinery or Presses for Molding Pail-Bodies or Variousother Matters from Paper-Pulp and I do'hereby declare the same to bedescribed in the following specification and represented in the ac- IOcompanying drawings, of which- Figure 1 is a vertical and transversesection of a machine or press embodying my invention, the nature ofwhich is defined in the claims hereinafter presented. Fig. 2 isahorizontal section, and Fig. 3 is a side elevation, on an enlargedscale, of parts of the tubes E and N, hereinafter described,with themechanism for moving the tube N downward and upward within the tube E.Fig. 4 is an under side view of the locking mechanism of the fo- 0formed,and consequently there is little, if any,

danger of bursting the water-proof fiexile or india-rubber bag or hoodthat surrounds the frustum. I

In Fig. 1 of the drawings, A represents a hollow hood or vessel, in theform, externally, of a conic frustum, or an approximation thereto, itbeing fastened to and supported on a flat annular base or ring, B,sustained by two or more uprights or legs, B, fixed to a floor, C.

O Projecting upward from the hood A, and arranged concentrically withthe head thereof, are two standards, D, between which, axially, isavertical tube, E, that, arranged in a stuffing-box, :0, supported bythe hood A, is fixed to and extends upward and somewhat downward fromthe head of the water-proof, fiexile, elastic, or india rubber hood F,that surrounds a foramiuous metallic hollow frustum, G, fastened to andprojecting upward from a circular base, H, having 1ugs a a to slide onguides b, proj ectinginwardly from the posts B.

From the central part of the base H a tube,

I, extends downward and slides watertightwithin a stationary tube, K. Apipe, 0, provided with a stop-cock, d, opens into the tube K, such tubeKbeing closed at its lower end and there provided with a stop-cock, andin practice is somewhat longer than the tube I. The pipe cis for theintroduction of steam, air, or water under pressure into the tube K, forthe purpose of forcing upward the tube I, the base H, and the frustum Gafter they may have been depressed for removinga pail-body from suchfrustum.

.Near the upper part of the tube I is a closure or partition, 0, abovewhich is a tubular neck,

d, that opens laterally out of the tube I. A

hose, e, leads from the neck 11 to another tubular neck, f, furnishedwith a stop-cock, g, and

leading out of a pipe, h, which is to be sup-l posed to communicate'withan air suction pump. Opening out of the neck fis a tube, 2', that alsoopens out of the bore of the tube E.

At its upper end the tube E is closed and abuts against the lower end ofa spiral spring, k, arranged in a case on the upper part of thestandards D. Above the spring there is screwed into its case a tubularcap or thimble, Z, to bear against the upper end of the spring and toregulate the pressure of the spring upon the head of the tube E. A ropeor chain, m, extends upward from the said head and over and partiallyaround a grooved guide-wheel, n, and thence downward, and -is fastenedto a toggle, 0, from which, at its lower end or part, a stud, 12,extends and slides freely within a slot or groove, q, made lengthwise ina lever, M, which is fulcrumed to a bracket, 1', fastene'd'to the baseB. When the lever hangs downwardly from thebracket, the head of the hoodF will be drawn and held up to that of thefrustum A. On turning upwardthe lever the tube E will be free to move downwardly, as occasion mayrequire.

\Vithin the tube E, lengthwise thereof, is a pipe, N, which at its lowerend is closed, ex-

cept in having one or more holes, 8, leading laterally out of it, justabove the closure t. The tube N at its upper part is bent laterally at aright angle,and extends through vertical openings or slots in the tube Eand standard D. Leading into the tube N is a hose, a, that communicateswith a pipe, 22, for supplying the machine with the stock or paper pulp.

IOO

freely on a screw-bolt, b, that goes through a short vertical slot, 0',in thetube E and screws into the tube N. A handle, d, projects from theslotted collar 10, which bears at its top against the bottom of thecollar *0, and also at its bottom against the top of the collar 00. Ontaking hold of the handle 02 and turning it one way the tube N will beforced downward within the tube E far enough to carry the holes 8 belowthe head of the hood F. From the collar a: there is an extension, 6', toclasp and slide on astationary straight guide, f projecting from one ofthe standards D.'

Preparatory to using the machine there is a thin woven cloth bonnetplaced upon the frustum G, so as to cover it closely on its top andsides, such bonnet being to prevent the pulp fibers from getting intoand choking the holes of the frustum. Surrounding the frustum at itslower part is a flat ring, h, beneath which headed rods z" projectdownward through the base H, through pockets or chambers k therein,there being within such pockets and to therods spiral springs Z, to drawthe rods downward. At a proper distance from and underneath these rodsare stops m, against which the heads of the rods bring up on the base Hand frustum G being depressed to a proper distance for .removal of apail-body from the said frustum. In the further descent of the said baseand frustum the bonnet and pail-body will be upheld by the ring andloosened from the frustum, so as to enable them (the said bonnet andpail-body and said ring) to be readily lifted off the frustum.

The base H is provided with mechanism for locking it in its highestposition. This mechanism (shown in under side view in Fig. 4) consistsof two sectoral cams, n, inclined on their lower surfaces and pivoted tothe lugs a. From each of them a shank, 0, extends, one of such shanksterminating in a handle, 1). Both shanks are connected by a rod, q,pivoted to them, so that on taking hold of the handle and moving it soas to turn its sectoral cam the other sectoral cam will besimultaneously and in like manner moved. These cams turn on andlofi theupper ends of the guides 12, and when turned on them, serve to effectthe locking of the base. By .turning the cams 0E to enable the spacewithin the hood and about the frustum G to be charged with thepaperpulp. On a sufficient amount of the pulp having been introducedinto the said space the tube N is to beraised, so as to stop the furtherflow of the pulp into the space. Next, the handle M is to be turnedupward, and steam or air or water under pressure is to be let into thespace surrounding the hood F, which may be done by means of a pipe, 1",provided with a stop-cock, s, and leading from aforce-pump orsteam-boiler, such pipe opening into the stationary hood A, such hoodhaving at its lower part a drainage-cock, a, and in its upper part anair-escape cook, '0 The pressure within the hood A will crowd the hood Fupon the mass of pulp, so as to firmly condense it upon the bonnet anddrive the surplus water through the frustum G. At the same time suctionthrough the pipes e and i is to be produced, so-

Next, the base H is to be unlocked and is to be depressed sufficientlyfor withdrawing the foraminous frustum G and the made pail-body from thehood F, and to enable the pail-body to be removed, with the bonnet, fromsuch frustum. After such may have been accomplished and the frustumbonneted, the said frustum and the base H are to be forced upward totheir highest positions relatively to the hoodsF and A, and the base isto be locked.

I do not claim, broadly, the foraminous frustum, its supporting-base,the 'flexile or elastic hood, and the surrounding inelastic hood,arranged as described, such being common to various other machines formaking pail-bodies or other like articles from paper-pulp.

1. The combination of the inelastic hood A,
